' FEEDER AND SEPARATOR FOR THRESHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 688,760, dated December10, 1901. Application filed November 24, 1900-. Renewed October 24,1901. S ial No. 79,862. (No modeli) To all whom it may concern:

Be it known that I, GEORGE E. WADLEIGH, of Detroit, in the county ofWayne and State of Michigan, have invented certain new and usefulImprovements in Feeders and Separators for Threshing-h/Iachines; and Ido hereby declare the following to be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to feeders and separators for threshing machines,especially bean-threshers.

The primary object of the invention is to provide means for separatingor removing stones or other foreign matter from the grain before thesame reaches the threshing-cylinder and also to prevent the stones fromdoing damage when acted upon by the separating means.

A further object is to provide improved means for insuring the passageof grain and fodder to the threshing-cylinder.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawing the figure is a vertical sectional viewshowing the receiving end of athreshing-machine equipped with myimprovement.

Referring to the drawing, 1 designates the frame of a threshing-machine,2 the threshing-cylinder, which is designed to be rotated in thedirection of the arrow indicated thereon, and 3 is a separating-drum setin advance of the threshing-cylinder on a plane above the latter-thatis, the separating-drum is located intermediate the threshing-cylinderand the point of introduction of the grain, so that the latter will besubjected to the action of such drum before its delivery to thethreshing-cylinder. This drum, which is designed to be rapidly rotatedin the direction of the arrow, (being the reverse of the rotation of thethreshing-cylinder,) is provided on its periphery with raised portionsor beaters 4. In advance of this separatingdrum is a receiving-table 5,over which travels an endless carrier 6, by which latter the grain isadvanced to the drum 3.

Mounted on the frame 1 and extending transversely thereof above theseparatingdrum is a hood 7, constructed to form a receiver and guard ordeflector for the stones thrown from the grain by the separatingdrnm, soas to arrest the same before they are discharged from the thresher.Thishood is shown as provided with two curved de-' fleeting-walls 8 and9, diverging from a point above and nearly in line with the rear vertical face of the separating-drum. The wall 8 extends upwardly andrearwardly, terminating in a vertical portion 10, which is secured to areceptacle 12, having two sides 13 and 14 and a slotted or perforatedbottom 15. Stones discharged into that portion of the hood outlined bywall 8 will fall into the receptacle 12, from which they may beremovedopening over which is suspended a flexible sheet 17, preferablyof canvas or other suitable material. Stones thrown by the separatingmeans into that portion of the hood described by wall 9 will strikeagainst the flexible sheet and, their force or momentum being arrested,will be received on the top 16.

18 is a receivingshoe located beneath the separating-cylinder anddesigned to receive the grain falling from such cylinder and thefeed-table and carry it to the threshing-cylinder. The reciprocatingmovement is imparted to this shoe by a rod 19, secured to a crank-shaft20. A deflector 21, located over the outer end of the receiving-shoe, isdesigned to deflect any foreign matter falling thereon which may belarger than the grain and carry it off from the shoe. This deflector maybe perforated or composed of spacedrect the fodder into the throat ofthe threshing-cylinder, and the fingers secured thereto allow the grainto pass from the receivingshoe to said cylinder.

The advantages of my improvements are apparent to those skilled in theart. It will be noted that a rapidly-operating separatingdrnm willeflectively separate stones and other foreign matter from the grain andthrow the latter upward against the hood, where they will accumulateeither in the stone-receiver or on the top of the thresher. It will alsobe noted that by locating the receivingshoe beneath the separating-drumgrain falling from the latter and the feed-table will be conveyed to thethreshing-cylinder and that the deflector-board will serve to preventany foreign matter larger than the grain itself falling thereon fromentering the shoe; also, that the transverse board and spaced-apartfingers will direct the fodder and grain to the threshing-cylinder, andthat beans thrown with the stones into the receptacle 12 will fallthrough the bottom of the latter back onto'the receiving-table carrier.

I claim as my invention- 1. In a threshing-machinehavingaseparating-drum in advance of the threshing-cylinder, a receptacledesigned to receive substances tangentially discharged by thecentrifugal action of said drum, and means intermediate of the drum andreceptacle for guiding and deflecting said substances into the latter,as set forth.

2. In athreshing-machinehavingaseparating-drum in advance of thethreshing-cylinder, an open-top receptacle designed to receivesubstances tangentially discharged by the centrifugal action of saiddrum,and means intermediate of the said top and in the line of dischargefor deflecting said substances, as set forth.

3. Inathreshing-machinehavingaseparating-drum in advance of thethreshing-cylinder, a receptacle for foreign substances discharged bysaid drum, and a hood having a curved wall for deflecting such foreignsubstances into said receptacle, as set forth. v

4. In a threshing-machine having a separating-drum in advance of thethreshing-cylinder, a receptacle, designed to receive foreignsubstances, &c., tangentially discharged by centrifugal action of saiddrum, having openings in its bottom for the passage of grain or beansfalling therein, and means for deflecting such foreign substances, &c.,into said receptacle, as set forth.

5. In a threshing-machine having a separating-drum in advance of thethreshing-cylinder, a feeding-table, a receptacle above said table,designed to receive foreign substances, &c., tangentially discharged bycentrifugal action of said drum, having openings in its bottom for thepurpose stated and means intermediate the drum and receptacle fordeflecting such foreign substances, &c. into said receptacle, as setforth.

6. In a threshing-machine having a separating-drum in advance of thethreshing-cylinder, a hood above said drum having an outletopening and areceiver for substances forced against said hood and through saidopening by said drum, as set forth.

7. In a threshing-machine having a separating-drum in advance of thethreshing-cylinder, a hood above said drum having an outletopening forforeign substances discharged by said drum, a flexible arrester betweensaid drum and outlet-opening and a receiver for substances forcedagainst said hood and beyond said arrester and opening by said drum, asset forth.

8. In a threshing-machine havinga separating-drum in advance of thethreshing-cylinder,a hood above said drum having oppositely extendedwalls forming deflectors for substances discharged by said drum, snbstamtially as set forth.

9. In a threshing-machine havinga separating-drum in advance of thethreshing-cylinder,a hood above said drum having oppositely= extendedwalls forming deflectors for substances discharged by said drum, one ofsaid walls forming an outlet, a receiver in line with said outlet, areceptacle to which the other wall is secured, and a flexible arresterdepending from said hood over said outlet, substantially as set forth.

10. In a threshing-machine having a separating-drum in advance of andabove the threshing-cylinder, a reciprocating shoe be neath said drum,and means over the outer end of said shoe for deflecting foreignsubstances from the latter, as set forth.

11. In a threshing-machine having a separating-drum in advance of andabove the threshing-cylinder, a reciprocating shoe beneath said drum,and a deflector over the outer end of said shoe fordeflecting foreignsubstances from the latter and formed with openings for the passage ofgrain onto the shoe, as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
